Description
Technical field
The present invention relates to a kind of quarry tippers, specifically, are related to a kind of front axle of mining dump truck structure.
Background technique
Off-highway quarry tipper is the prevailing traffic equipment of large surface mine, and its structure is complicated, working environment is severe.
Front axle of mining dump truck as the important component in entire mine car running gear, the superiority and inferiority of structural behaviour to it is mining from
The operation and maintenance unloaded has important influence.
As shown in Figure 1, being front-axle structure schematic diagram in the prior art；As shown in Fig. 2, be in the prior art A-A to cut open
Face schematic diagram.
Front-axle structure is integrally in " recessed " shape, mainly by body of a bridge welding girder, outstanding cylinder support, tie rod support, longitudinal tie branch
Seat composition.Wherein body of a bridge welding girder is welded by upper plate 1, lower plate 2, two blocks of front and back web 3 and welding liner plate 4.
It is connected between upper plate 1, lower plate 2 by two blocks of front and back web 3, upper plate 1 passes through with two blocks of front and back web 3
Welding liner plate 4 welds together, and lower plate 2 is welded together with two blocks of front and back web 3 by welding filler strip 5.Web 3 is at turning
Transition position has out the slot of certain length, is welded together by sealing weld and welding liner plate 4, these are provided to reinforce original knot
The intensity of structure corner, and reality can not still make up stress concentration phenomenon caused by its own structure.
Existing front axle of mining dump truck all uses whole square-box-shaped welded-steel plate construction, and both ends are in the small bend angle transition of " Z " type
There is stress concentration at small bend angle in use, so structural-load-carrying capacity is not strong, weld seam be easy to cause to open in structure, this structure
Phenomena such as splitting.And as market of the off-highway quarry tipper to more large-tonnage vehicle needs, so that front-axle structure intensity at present
Problem more highlights, and has been unable to meet the requirement of vehicle safety reliability service.
Summary of the invention
Technical problem solved by the invention is to provide a kind of front axle of mining dump truck structure, so that the bearing capacity of structure
It is significantly promoted, service life lengthens significantly.
Technical solution is as follows:
A kind of front axle of mining dump truck structure, including the body of a bridge weld girder, the body of a bridge welding girder include: arc upper plate,
Arc lower plate, arc-shaped webs are connected between arc upper plate, arc lower plate by two pieces of arc-shaped webs, link position
It is connected with welding filler strip；Body of a bridge welding girder is integrally in the smooth transition of dome-shaped orthodrome, and arc upper plate, arc lower plate exist
Bending position is excessive using arc, and the top and bottom of arc-shaped webs are arc-shaped side.
Further, arc upper plate, arc lower plate, arc-shaped webs form body structure, inside four by welding manner
Angle is overlapped using welding filler strip.
Further, arc upper plate, arc lower plate by monolith steel plate rolling be dome-shaped, the top of arc-shaped webs and
Bottom is arc-shaped side, and the shape of arc-shaped side and arc upper plate, arc lower plate is adapted.
The technology of the present invention effect includes:
The present invention is in the case where guaranteeing the not increased situation of front-axle structure own wt, by the change and optimization of structure type,
20% or more bridge stress intensity before increasing.It eliminates and is welded at the reinforcement liner plate and its small round corner of the inside configuration of original preceding bridge
Liner plate, to simplify structure, at the same make it is entire before bridge be more uniformly stressed, structural strength is big, long service life.
1. front axle of mining dump truck body of a bridge structure is changed to as dome-shaped by the present invention, so that structural-load-carrying capacity is significantly
It is promoted, service life lengthens significantly.
2. the present invention jumps out reinforces the usual thinking of front axle of mining dump truck intensity by increasing thickened material in the past, and
Do not increase body of a bridge own wt using the modes such as reinforcing rib are welded with, while so that structure is simpler, also increases vehicle
The fuel-economy type of load capacity and vehicle operation.
3. the present invention has simplified no longer necessary reinforcement liner plate reinforcing rib etc., has reduced processing work after structure optimization
Skill process, thus reduce production cost.
4. the present invention is applicable not only to quarry tipper field, it could be applicable to other heavy and engineering trucks, use model
It encloses very extensive.
Detailed description of the invention
Fig. 1 is front-axle structure schematic diagram in the prior art；
Fig. 2 be in the prior art A-A to diagrammatic cross-section；
Fig. 3 is the schematic diagram of quarry tipper front-axle structure in the present invention；
Fig. 4 is the diagrammatic cross-section of quarry tipper front-axle structure B-B direction in the present invention.
Specific embodiment
Be described below and specific embodiments of the present invention be fully shown, with enable those skilled in the art to practice and
It reproduces.
The present invention changes existing " recessed " the shape structure of the front axle of mining dump truck body of a bridge in the prior art, creative proposition
New domes, the arch body of a bridge is moulded smooth, without the singular point in stress, so that stress is uniformly distributed on the body of a bridge,
Preceding bridge itself has been greatly reinforced by loading capability.Meanwhile it being further simplified due to the not enough reinforcement liner plate to be welded with of intensity before
Equal components, so that structure and manufacturing procedure are simpler.
As shown in figure 3, being the schematic diagram of quarry tipper front-axle structure in the present invention；As Fig. 4 be in the present invention it is mining from
It unloads the diagrammatic cross-section of front-axle structure B-B direction；
The structure that its body of a bridge of front axle of mining dump truck structure welds girder includes: arc upper plate 6, arc lower plate 7, arc
Shape web 8 is connected between arc upper plate 6, arc lower plate 7 by two pieces of arc-shaped webs 8.Under arc upper plate 6, arc
Bottom plate 7, arc-shaped webs 8 form body structure by welding manner, and internal quadrangle is overlapped using welding filler strip 9.Body of a bridge weldering
Connecing girder integrally is in the smooth transition of dome-shaped orthodrome, and arc upper plate 6, arc lower plate 7 use arc mistake in bending position
Degree, the top and bottom of arc-shaped webs 8 are arc-shaped side, and arcuate structure disperses stress more, solves and exist in the prior art
The defects of stress collection of each corner is welded with liner plate without itself aperture of web 3 and inside.
Arc upper plate 6, arc lower plate 7 are dome-shaped, the top and bottom of arc-shaped webs 8 by the rolling of monolith steel plate
For arc-shaped side, the shape of arc-shaped side and arc upper plate 6, arc lower plate 7 is adapted.
It should be understood that the foregoing is merely a specific embodiment of the invention, but protection scope of the present invention is not
It is confined to this, anyone skilled in the art in the technical scope disclosed by the present invention, can readily occur in variation
Or replacement, it should all be included within the scope of the present invention.Therefore, protection scope of the present invention should be with the claim
Protection scope subject to.
